The inductor in high frequency of main flow, it is limited by the performance of product structure and magnetic material.The high inductor through-current capability of applying frequency compared with
Weak, the strong inductor applying frequency of through-current capability is low.In addition, traditional I-shaped inducer uses common circular copper wire coiling, circle
The window utilization rate of copper cash is relatively low, furthermore traditional I-shaped inducer uses and scalds process of tin, in boiling hot tin operation, to remove circle copper
The coat of paint on line surface easily causes wire surface insulating barrier, it is necessary to higher boiling hot tin temperature, heat are acted on enamel insulated round copper wire
Melting loss, there is short circuit problem.
Utility model content
For above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of based on the I-shaped of flatwise coil
Inductor in high frequency, to realize the applying frequency of through-current capability stronger under same volume and Geng Gao.
To achieve these goals, the technical solution adopted in the utility model is：It is a kind of based on the I-shaped of flatwise coil
Inductor in high frequency, the winding that it is formed by a T-shaped magnetic core, an I shapes magnetic core and a coil are formed；The T-shaped magnetic core
Top is provided with the magnetic core top of disc-shaped, and the magnetic core bar of pole shape is provided with the bottom of T-shaped magnetic core；Its entirety of the I shapes magnetic core is in
Square sheet, two identicals are provided with the lower surface of I shape magnetic cores and by the pad of nickel bottom roasting silver processing；The coil by
Flat enamel-covered wire turns to, and is bonded together again with magnetic core after coil entirety coiling shaping, coil main body portion is provided with coil
Point and coil lead part, the pad solder on its coil lead part and I shape magnetic cores, its coil main body part is located at I shape magnetic
Above core, its magnetic core top is located at coil main body upper, and its magnetic core bar is located at coil main body partial interior.
Preferably, the cross section of enamel-covered wire and the cross section phase of lead on coil lead part on the coil main body part
Together.
Further, two width identical short slots are additionally provided with a side of the I shapes magnetic core, the width of its short slot is more than
The width of flat enamel-covered wire, coil lead part pass through short slot and pad solder.
Further, the diameter on the magnetic core top is less than the length of side of I shape magnetic cores.
Further, the length of the magnetic core bar is less than the height of coil main body part.
During real work, according to the correlation technique of Faraday's law, and soft magnetic materials, magnetic flux is in magnetic core
Loop is formed, realizes the function of inductor.
Using the I-shaped inductor in high frequency of the technical program than traditional inductor in high frequency, have following obvious excellent
Gesture：
1st, higher window utilization rate, more excellent through-current capability is obtained：Traditional inductor in high frequency is using common circle copper
Line coiling, the window utilization rate of circular copper wire are less than flat copper wire, and the process window shared by 4 strands of 0.4mm enamel-covered wires compares 0.4*1.2mm
Much more flat 33%；
2nd, short-circuit hidden danger substantially reduces：Traditional inductor in high frequency, in boiling hot tin operation, is justified using process of tin is scalded to remove
The coat of paint of copper line surface easily causes wire surface to insulate, it is necessary to higher boiling hot tin temperature, heat are acted on enamel insulated round copper wire
, there is short circuit problem in the melting loss of layer, and uses flat enamel wire coil, divested by cutter after the paint film of coil welding position
Welded, welding effect can be achieved with relatively low scolding tin temperature；Meanwhile because the mechanism for removing coat of paint is different, flat paint
Envelope curve can use the higher isolation material of heat resistance；
3rd, structural strength is more preferable：Traditional inductor in high frequency is needed by copper wire winding on magnetic core center pillar, when line footpath is thicker
When, magnetic core center pillar needs to bear bigger stress, the hidden danger that magnetic core fracture be present, and this I-shaped inductor in high frequency is that coil is whole
Bonded together again with magnetic core after body coiling shaping, magnetic core caused by can effectively evading stress is broken；
4th, more preferable heat-sinking capability：The coiling of traditional inductor in high frequency needs the reciprocal lamination coiling in magnetic core window,
Cause the radiating condition of inner coil worse, this I-shaped inductor in high frequency is by flat copper wire helical form coiling, each circle coil
More excellent radiating condition can be obtained with contacting external air.
